Can you explain this vulnerability to me?
This vulnerability is a stored cross-site scripting (XSS) issue in the Foxit eSign section of pdfonline.foxit.com. It occurs in the Predefined Text feature where an attacker can insert a malicious script payload into the Identity 'First Name' field. This payload is stored and later rendered into the web page's DOM without proper sanitization, allowing the script to execute when predefined text is used or when viewing document properties.
How can this vulnerability impact me? :
The vulnerability can allow an attacker to execute malicious scripts in the context of the affected web application. This can lead to unauthorized actions such as stealing user session data, defacing content, or performing actions on behalf of the user, potentially compromising user data confidentiality and integrity.
